The VQFN package provides access to internal nodes of the circuit as shown in Figure 9-3. Capacitors can be placed on these pins and AVDD to form a filter on the output current, reducing bandwidth and the slew rate of the output. However, to achieve large reductions in slew rate, the programmable slew rate can be used to avoid having to use large capacitors. Even in that case, the capacitors on CAP1 and CAP2 can be used to smooth out the stairsteps caused by the digital code changes as shown in Figure 8-7. However, note that power supply ripple also couples into the part through these capacitors.
